Typewriter



Patented May 17, 1932 UNITED STATES PATENT" v OFFICE Application filed February 7, 1931, SeriaLNo.

This invention relates to typewriters and particularly concerns the carriage and paper rest thereof. Its main object is to provide an improved arrangement of the said paper rest and of the marginal stops in connection therewith.

I Another. object of the invention is the provision of the improved paper rest and of the stop mechanism in a manner which will enable their convenient arrangement in aclosely confined space and to move out-of position when not in use.

A further object of the invention is the arrangement of the marginal stops in such a manner as will avoid the necessity of special release means being provided.

With these and other objects in view the invention consists in the provision and arrangement of parts hereinafter more fully described and illustrated in the accompanying sheet of drawings which, by way of example, represents an embodiment of the invention as applied to a portable typewriter,

' and in which Fig. 1 is a fragmentary cross section through the rear portion of a typewrlter, while Fig. 2 is a plan view of the improved paper rest and marginal stop mechanism.

Referring to Fig. 1, a is the platen of the typewriter whichis carried in lateral brackets b of the typewriter carriage c. Pivoted to the said brackets at the rear of the platen are two arms d to'which the paperrest e is rigid- I 1y secured. As will be seen, the said paper rest consists of a relatively high sheet metal plate which, when inuse, takes an inclined position, in which it leans with its lowermost edge f firmly against the rearward edge 9 of the paper guide 7L. This position is shown. in full lines in Fig; 1.

When the typewriter is not in use and, in the case of a portable typewriter, is enclosed in its case 2' as indicated by the dot and dash lines, the paper rest e is swung about its hinge pins k into the approximately hori-' zontal position shown in dotted lines in Fig. 1, in which it rests directly above the platen a within the profile of the machine and, so

514,078, and in Germany February 10, 1930. as not to impede the typewriter being locked "into its case.

The arrangement just described enables the employment of a relatively high paper rest without "any additional extensions of wire or the like. into the shape of the machine is of particular advantage in connection with portable typewriters, in which a compact arrangement of parts is of utmost importance in view of the required small size of the whole typewriter and its case.

The fact of its folding-up closely Along the lower edge of the paper rest e I atthe back thereof and at a short distance therefrom a rack Z is arranged, which is preferably carried in the lugs or brackets d of the carriage, while a graduated scale m is directly attached to the paper rest in opposition to the rackl. Upon the latter two marginal stops a are arranged so as to slide along the said rack and to resiliently engage into the teeth of the same in substantially known manner. The said stops limit the to and fro movement of the carriage by coming into contact with fixed abutments oprovided 'on the machine frame under-neath the paper rest.

The arrangement of the marginal stops in connection with the paper rest is of con siderable advantage. Thus, shifting the stops may be effected by simply swinging the paper rest in the out-of-use position, when they are readily accessible to' the writer sitting in front of the machine. Stop release after contact with the abutments o is efiected by simply tiltingthe paper rest forward until the nose 3) in contact with the abutment leaves same and the carriage becomes free to continueits travel either by the action of writing or by being shifted by hand. After v the release of the stops the paper rest again takes its normal working position shown in full lines in Fig. 1. In this way the usually provided special release means are rendered unnecessary."

Vhat I claim is v 1. In a typewriter coi'nprising a carriage and a hinged'paper rest, lateral-brackets to said carriage for the support of the platen, pivoted arms on said brackets, a paper rest rigidly attached to said arms, and means in connection with said paper rest to adjustably support marginal stops thereupon. 2. In a typewriter comprising a carriage and a hinged paper rest, lateral brackets to 5 said carriage for the support of the platen, pivoted arms on said brackets, a paper rest rigidly attached to said arms, a rack at the lower side of said paper rest, marginal stops resiliently carried on said rack, and a graduated scale also at the lower side of said paper rest in opposition to said rack.

3. In a typewriter comprising a carriage and a hinged paper rest, lateral brackets to said carriage for the support of the platen,

pivoted arms on said brackets, a paper rest rigidly attached to said arms, a rack at the lower side of said paper rest at a short distance therefrom, marginal stops resiliently carried on said rack, and a graduated scale closely fastened to the lower side of said paper rest in opposition to said rack.

4. In a typewriter, a carriage, lateral brackets to said carriage for the support of" the platen, a pivot in each of said brackets at the rear of the platen, swing arms turnable in said pivots. a paper rest rigidly secured to said arms, and means at the lower side of said paper rest. to adjustably support marginal stops thereupon, said stops working in conjunction with fixed abutments on the machine frame. v

5. In a typewriter, a carriage, lateral brackets to said carriage for the support of the platen, a pivot in each of said brackets at the rear of the platen, swing arms turnable in said pivots, a paper rest rigidly secured to said arms, a rack at the lower side of said paper rest, marginal stops resiliently car-- ried on said rack, a graduated scale also at the lower side of said paper rest-in opposition to said rack, and fixed abutments on the machine frame in the path of said marginal stops.

In testimony whereof I afiix my signature. 45 HERBERT ETHERIDGE.
